Reduction of Minimum Cutting Thickness of Titanium Alloys in Micro Cutting by a Magnetic Field Assistance

IEEE Access, 2019
Ultra-precision diamond cutting (UPDC) is a promising machining technology to generate precise components with optical grade surface. However, a tool rake angle turns to be negative when the tool radius is significantly larger than cutting depth during ...

Theoretical Analysis of Undeformed Chip Thickness for Multi-Axis Ball-Nosed End Milling.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 2001
This paper presents a new analytical method to estimate the thickness of an undeformed chip in ball-nosed end milling. It has been firstly pointed out that the geometric situations on the determination of the thickness are categorized in three cases based on the relationship among the milling parameters.

On‐Chip Evaluation of Red Blood Cell Deformability Through Transit Velocity Index in Hematological Diseases

Small, EarlyView.
The deformability of red blood cell is essential for smooth microcirculation. We propose a deformability index using a microfluidic platform with capillary‐like constrictions, based on the relationship between cell deformation and transit velocity through the constrictions. Its effectiveness and clinical potential have been demonstrated in applications
